What are the production processes for PVC particles and what are the production processes for PVC particles

Release date:2020-10-29 Number views:13

PVC particles are made of high-quality PVC resin powder as the substrate, and are used in stabilizers, lubricants, colorants, impact agents, and other additive applications. Therefore, the production process is also quite complex. Today, we will introduce to you the production process of PVC particles, which are full of dry goods. We suggest that you collect them.


1、 Before granulation, the weighing and blending of powder and various additives are also relatively strict, and the quality error of the product is required to be within a certain range.


2、 The initial plasticization of the material is achieved through the mixing of high mixed steel during the plasticization process, followed by the force making process. There are also strict requirements for processing temperature and current during this process.


3、 The weighing and packaging process, followed by the Z step, is the warehousing process. After dozens of quality control steps, a package of qualified particles is successfully completed.


According to your requirements, you can provide us with both density and color or this color palette, and we can customize this piece. The production line we use is a parallel and co rotating twin screw twinning machine that extrudes the entire process of air-cooled cutting particles, without contact with any moisture throughout the process. Eliminating the occurrence of water splashes during injection molding and the drying time will greatly shorten the process. The density is 1.32 to 1.38, which can be customized according to your requirements. It meets the ROHS and REACH standards for environmental protection, which means that it does not contain 16P, does not contain phthalic acid, and does not contain heavy metal pollution. Last year, I used our black material to make samples at an injection molding factory. The samples made from this material had a very high surface gloss. There is no watermark appearing on the imported material, including this one.
